Be aware that You operate CW on the K3 and KX3 using an app called K3iNetwork 
made by Mike KS7D. I have used it extensively over the last 18 months. Right 
now actually using it from EA8 :-) Mike is working on another app which uses 
the touch screen as a touch paddle. It still not working too well but I think 
it will be improved soon.
